Handling
1. Corrosive material — avoid contact with skin, eyes, and clothing.
2. Do not breathe vapors, mist, or fumes.
3. Use only in well-ventilated areas or with local exhaust ventilation.
4.Wear appropriate PPE: acid-resistant gloves, chemical goggles/face shield, protective clothing, and respiratory protection if required.
5. Use corrosion-resistant equipment (e.g., stainless steel or lined systems).
6. When diluting, slowly add acid to water — never add water to acid.
7. Avoid contact with strong bases, oxidizing agents, and reactive metals.
8. Wash thoroughly after handling.
Storage
1. Store in a cool, dry, well-ventilated area.
2. Keep container tightly closed when not in use.
3. Store in corrosion-resistant containers (e.g., carbon steel, stainless steel, or lined tanks suitable for PPA).
4. Protect from moisture (reacts with water and generates heat).
5. Keep away from incompatible materials such as alkalis and reactive metals.
6. Provide secondary containment to prevent spills.
7. Follow local regulations for storage of corrosive acids.
